Colostrum should not be saved from a mare with a history of having a foal affected by neonatal isoerythrolysis (NI or Jaundice Foal Syndrome) or that died from unknown causes within the first few days after birth. . Brix refractometers are easy to use, require a minimum of colostrum (i.e. one drop) and results are highly correlated with IgG .A new, simple and pocket-sized tool will now help to assess colostrum quality and therefore lower the risk of failure of passive transfer. The H&L Refractometer works by using light to determine the density of a liquid. Meaning, a sample of the examined liquid such as the colostrum or even blood serum is shined through with a beam of light.Colostrum Refractometer is ideal for the measurement of IgG levels in colostrum. Only a few drops of colostrum are required and the entire test can be completed in less than a minute. It features automatic temperature compensation for enhanced accuracy over an operational range of 10ºC – 30ºC (50ºF – 86ºF).
Poor quality colostrum is typically white and watery. Colostrum can also be measured objectively and more accurately using a colostrometer or refractometer (Brix or alcohol). Typically sugar (Brix) refractometers allow easy and precise assessment of colostrum quality on-farm. Good quality colostrums ≥ 20% with the sugar (Brix) refractometer.
Evaluation of mare colostrum immediately after foaling and prior to nursing can be helpful in predicting if failure of passive transfer is likely to occur e.g. when colostrum has been lost due to premature leakage from the mammary gland, or if the colostrum quality is poor. . The cost of a Colostrum refractometer test is approximately .Brix refractometry score (percentage) for colostrum from 10 individual postpartum mares The correlation coefficient (r) between SRID values and Brix scores for all 56 mammary fluid samples was 0. . Linear regression modeling showed that refractometer data were related to RID (r = 0.78). Results obtained suggest that breed and parity can influence IgG content of colostrum and, despite the Brix refractometer being an excellent on-farm tool, a breed-based definition of optimal cut point is needed.

To evaluate colostrum using the equine colostrum refractometer, a small amount of colostrum is collected (Figure 1), and one to two drops are placed on the prism (Figures 2 and 3) and the daylight plate is closed. . However, if it can be determined that the quality of the colostrum produced by a mare is inadequate, the foal can be . Brix refractometer and colostrum IgG content ELISA IgG (0 to 3 h, mg/ml) IgG estimation Brix % (average ± SEM) categories <20 14.5 ± 1.8 Poor 20 to 24 43.8 ± 2.3 Borderline 25 to 29 50.7 ± 2.1 Adequate .30 78.6 ± 8.4 Very good Validation of the Brix refractometer A total of 153 samples taken at 0 to 3 h from farrowing were assessed for . Mare colostrum is composed by a large amount of nutritional and immune components, most of which are represented by immunoglobulins G (IgG) isotype. . of the present study was to evaluate the relation between colostrum IgG concentration evaluated by SRID and the Brix refractometer in the donkey colostrum and to establish a cutoff value for .immunoradiodiffusion,8 or immunoturbidimetric assay.17 In addition, the Brix refractometer score of mare colostrum collected immediately after foaling has been reported to be correlated with IgG in foal plasma collected 12 - 48 hours after birth.17 Other reasons for evaluation of mare colostrum besides prevention of failure of passive transfer
The ARS Equine Colostrum Refractometer is a portable instrument for analyzing mare colostrum quality. Only a few drops of colostrum are required and the entire test can be completed in less than a minute. The ARS Equine Colostrum Refractometer features automatic temperature compensation for enhanced accuracy over an operational range of 10ºC .
immunoradiodiffusion,8 or immunoturbidimetric assay.17 In addition, the Brix refractometer score of mare colostrum collected immediately after foaling has been reported to be correlated with IgG .To ensure maximum antibody protection is given to new-born foals/calves, 2-to-4 litres of good quality colostrum should be fed in the first 12 hours of life. Colostrum quality can vary significantly from horse to horse. This BRIX-scale . In calves fed a colostrum replacer, the ratio of fat to protein and IgG to protein is different than in fresh maternal colostrum, resulting in inaccurate results on a refractometer. In calves with dehydration , the blood volume is .
Colostrum refractometers are valuable tools for dairy farmers to assess colostrum quality and make informed decisions regarding calf health and immunity. They help ensure that newborn calves receive high-quality colostrum, which is vital for their overall well-being and future productivity. It’s recommended to follow the manufacturer’s .To ensure maximum antibody protection is given to new-born foals/calves, 2-to-4 litres of good quality colostrum should be fed in the first 12 hours of life. Colostrum quality can vary significantly from animal to animal. This BRIX-scale refractometer enables you to easily test colostrum quality for cow or mare milk.The colostrometer, which measures the specific gravity of colostrum, is the most commonly used on-farm method to assess colostrum quality. Yet, the colostrometer is a fragile instrument, and is not accurate on refrigerated or warm colostrum3. The Brix refractometer has been used to assess the colostrum of mares, resulting in a high correlation

The quality of mare colostrum was determined with a digital Brix refractometer (McCue, 2014). The teats of the mare were cleaned with an alcohol swab, and a small amount (1-2 mL) of colostrum was .
Serum total protein was also positively correlated with %Brix (r = 1.00) and IgG (r = 0.93). Dairy producers can successfully monitor their colostrum management and the overall success of passive transfer using a digital Brix refractometer to .
HOW TO CALIBRATE A MANUAL REFRACTOMETER. USES FOR A BRIX REFRACTOMETER ON THE FARM. COLOSTRUM QUALITY —Fresh colostrum can be tested using a refractometer for adequate levels of immunoglobulins to ensure that your calves will get off the right start. Colostrum measuring 22% or higher is generally considered high quality.
The first meals ingested by a healthy foal consist entirely of colostrum, the nutrient- and antibody-packed fluid produced by the mare during the first hours after birth. Thicker, yellower, and stickier than milk, colostrum quality sets the tone for foal health in the coming days and months. High-quality colostrum nourishes foals and protects them from [.] To assess the optimal cut-offs for the optical (OR) and digital (DR) refractometer and determine their accuracy for poor quality colostrum diagnosis. Study design. . The average IgG concentration measured by RID in mare colostrum was 95.91 ± 45 g/L with variability among breeds that was not statistically significant; 93.53 ± 32.43 g/L for . Summary The evaluation of mare colostrum immediately after foaling and prior to nursing can be helpful in predicting if adequate passive . This chapter discusses step by step procedure for performing the evaluation of colostrum using Brix refractometer. It also discusses necessary conditions for evaluation of colostrum using Brix .
This BRIX-scale refractometer enables you to easily test colostrum quality and the levels of antibodies, also known as colostrum immunoglobulin’s (IgG), in the quality of cow or mare milk. After checking calibration of the instrument with distilled water, two drops of the colostrum to be tested are placed on the glass prism.
